Predators defenseman Alexander Sulzer has a separated left shoulder and is expected to be out three to four weeks, according to coach Barry Trotz.

Sulzer was playing in only his 2nd NHL game last night in Vancouver, when former Pred Darcy Hordichuk hit him along the boards early in the 1st period. While Greg de Vries appears to be about ready to rejoin the lineup, this will likely put a damper on some of the trade speculation that’s been bandied about wherein Nashville would part with a defenseman in order to bolster the offensive attack up front.
